A comprehensive guide to Nmap with screenshots and example

What is Nmap?

Nmap (”Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Nmap runs on most types of computers and both console and graphical versions are available

I love how this "comprehensive" guide is nothing more than http://insecure.org/nmap/man/man-briefoptions.html with pictures. Way to copy! :D

I've moved this thread from Security Tutorials as that's for original work. While this may still be of benefit to others, I don't see it as a tutorial per say.

If you look carefully I did mention the source.
